Eight-Channel Video Mixer with Effects


The V-8 is the natural evolution of the legendary V-4 four-channel video mixer

The V-8 offers an expanded visual experience and is the natural evolution of the legendary V-4 Four Channel Video Mixer. The V-8 Eight Channel Video Mixer has all the features of the V-4 but with more channels, two selectable RGB inputs, monitor outputs and additional powerful special effects. It continues the legacy of the V-4's other great features such as ease of use, high-quality digital processing of video, numerous video effects and BPM sync with music. This next generation video mixer expands your visual presentation and performance potential to new applications and dimensions.

DV quality video outputs with full digital processing

The internal processing of the V-8 is 4:2:2 full-frame digital. More than 500 lines of video resolution ensure very high image quality after digital processing and mixing.

Direct input of computer signal

The V-8 has a built-in scan converter, providing direct input of RGB signals (VGA - UXGA) from two D-Sub terminals on the rear panel. With the selector switch located on the top panel, you can select between two computer sources. Using the luminance key or chroma key, enables logos or text from your computer to be keyed over background video enabling the display of lyrics, bottom thirds, and announcements. Integrating computer graphics and visual applications with video sources has never been easier.


New video filters and numerous transitions

All your favorite effects like colorize and negative are included, along with newly added effects like feedback, afterimage, emboss, find edge and more. Composite two images with Picture-in-Picture and Luminance or Chroma keying. Customize your transitions between the A and B bus with multiple flavors of simple mix, hard or soft wipes, and the all-new stretch and slide transitions.

Independent faders on each bus as well as master output

Faders are independently equipped for both A/B buses allowing you to create a video fade on just one bus or adjust the various video effects parameters. The master fader control is a slider bar enabling quick and intuitive operation while working on the fly.

Next generation V-LINK control enables audio-follow

The V-8 can be remote controlled from the Roland PR series video presenters as well as the V-4. The V-8 can also send remote control signals to the new generation of Roland's digital audio mixer, the M-400 or M-380 V-Mixer . The motorized faders of the M-400 automatically follow the video switching of the V-8. Now you can have your audio sources follow your video sources without the need to manually control two mixers at once.

Concerts or VJ Performances Example

Images can be projected on a large screen located at the back of the stage to create a video performance that’s synchronized to the music. You can mix images from a P-10 Visual Sampler, PR-50 / PR-80 Video Presenters or computer (VJ software) with multiple live images.

Background Video for a Musical Performance Example (Using V-LINK)

You can control background video (BGV) simultaneously while playing an instrument.
